Supercharger Battery Pack for Retra Flash Announced
By Ian Bongso-Seldrup, June 8, 2020 @ 08:00 PM (EST)

Retra has unveiled a new battery pack for their Flash PRO and Flash Prime strobes. Appropriately named the Supercharger, the battery pack reduces recycle time by more than half and gives you more than double the number of flashes per charge. With the Supercharger (and eneloop pro batteries), recycle time to 80% power is about 1.5 seconds (compared to around 3 seconds without) and you can fire the flash about 350 times at full power (versus approximately 150 times without).

According to Retra, the mounting of the Supercharger to the strobe is “super robust”—so much so that the photographer can “hold onto the Supercharger when adjusting the flashgun underwater.” Double O-ring seals ensure peace of mind. Like the flash itself, the Supercharger takes four AA batteries, for a total of eight.

The Supercharger is priced at €239 (ex. VAT), but if you pre-order from Retra now, you pay only €199 (ex. VAT). You can also pre-order the Flash PRO and Supercharger together for €1,029 (ex. VAT) and save €100. Retra will extend your Flash Prime or PRO warranty by six months when you purchase the Supercharger. You can also purchase the Supercharger from Backscatter at the sale price of $230.

Users of the original Retra Flash should note that the Supercharger is not compatible with their strobe: The Supercharger can only be used with the latest Flash Prime and Flash PRO.
